Is this normal?
I imagine it would be more effective to suck in cooler air from below and exhaust it above.
My EasySolar II GX 48/3000/35-32 rapidly derates (or at least, gives Overload warnings) even under modest load, even in winter in an unheated shipping container with ambient temperature ~10C. The fan runs, but blows a little hot air out below (working against the natural buoyancy of hot air). The easySolar is probably getting hot inside. Is the airflow direction a factor in this?
